A-SCAN PLUS

Accutome
■ The A-Scan Plus is an effective solution for measuring and calculating patients and refining surgical outcomes for cataract surgery. It has the ability to measure all patients, including those with dense cataracts and fixation difficulties. The A-Scan Plus has the best resolution and largest screen size available for precise and reproducible axial length measurements, according to Accutome. The automatic personalization of lens constants can help users achieve superior surgical outcomes and the alignment detection feature eliminates marginally aligned scans.

The software makes it possible to store up to 100 patients' measurements and uploads to a paperless office or EMR. In addition, it includes modern third-generation formulas such as the Hoffer Q, SRK/T, Holladay and Haigis, as well as new post-refractive formulas.

IOLMASTER

Carl Zeiss Meditec
■ The IOLMaster has emerged as the standard of care where precise refractive outcomes are essential, as with the new multifocal and accommodative IOLs, says CZM. This easy-to-use, non-contact, all-in-one instrument measures axial length, corneal curvature, anterior chamber depth and white-to-white. IOL power calculations include third- and fourth-generation formulas as well as post-refractive surgery and phakic IOL modes. The enhanced platform offers new networking options and increased measurement speed and an integrated lens constant optimization program allows for efficient personalization to enhance outcomes. Software version 5 (Advanced Technology Software) simplifies operation through improved signal processing in axial length mode and signaling of the optimal measurement setting in keratometry.

PRAGER SHELL

ESI, Inc.
■ ESI, Inc. is the exclusive manufacturer of the Prager Shell for immersion biometry, offering nine different models. Prager Shell models are manufactured according to each A-scan manufacturer's specifications for consistent and accurate probe placement.

ESI's proprietary and patented design automatically positions the ultrasound probe perpendicular within the shell, and at the correct distance from the eye, insuring an optimum scan, says the company.

To reduce the potential for patient cross-contamination, an integrated luer connector is located on the side of the instrument for easy replacement of the used contaminated Prager Shell tubing kit. Sterile replacement kits are offered both with and without a one-way flow check-valve.

PALMSCAN AP2000

Micro Medical Devices
■ PalmScan is a battery-operated, fully portable, ultrasonic A-Scan/pachymeter combination biometer. Its pocket size, 8.4-ounce weight and easy operation afford the freedom to treat patients anywhere or check biometry before surgery, says Micro Medical.

The AP2000 features contact and immersion biometry with automated visual axis alignment, modern IOL formulas and post-refractive correction of keratometry. PalmScan's pachymeter offers central and peripheral corneal pachymetry with IOP adjustment calculator. PalmScan's optional LRI package includes a 50MHz probe and facilitates the planning of LRIs.

This package also includes a built-in age- and pachymetry-adjusted nomogram, user-customizable nomograms and concurrent cataract and LRI vector analysis. PalmScan is also capable of performing direct measurement of femtosecond laser flaps prior to lifting of the flap. Integrated desktop software allows archiving, viewing and printing of patient reports. Bluetooth printing technology allows wireless printing of reports to office printers.

US-4000 ECHOSCAN

Nidek, Inc.
■ The Nidek US-4000 EchoScan is a comprehensive ultrasound, which includes A/B-scan, biometry and pachymetry in a compact, lightweight device. High-resolution images are achieved through 400 lines of sampling over 60° and displayed on a 1024 × 768 XGA, touch-panel monitor. High-density scanning sectors provide ideal images for the most accurate diagnosis, says Nidek.

Using state-of-the-art algorithms, anterior chamber depth, axial length measurements and IOL power calculations are performed rapidly and accurately. Accurate measurements for dense cataracts are accomplished by pressing the "Dense Cat" and "Gate Select" switches. The pachymetry mode offers precise measurement of corneal thickness within a maximum ±5 mm.

A-SCAN DB-3100

Ocuserv Instruments, Inc.
■ A-Scan DB-3100 is designed to be the most versatile unit for ultrasonic biometry and IOL power calculations, says Ocuserv. Using a computer for data entry, display and memory enables the DB-3100 to retain information on an unlimited number of IOLs, physician profiles and patient data.

The intraocular distance measurement can be performed using either contact or immersion methods in auto or manual mode. Pattern recognition algorithm in automode selects scans along the visual axis. All scans performed are stored in patient files.

IOL power calculations are performed using the HofferQ formula, which provides comparative results to SRK/T and Holladay formulas. It allows up to five IOL styles per calculation.
